Title: Pharmaceutical composition comprising mesenchymal stem cell expressing trail and cd as effective ingredient for prevention or treatment of cancer
Inventor: JEUN SIN-SOO
IPC: C12N5/0775
Filed: 2018-08-06
Abstract: The present invention relates to a pharmaceutical composition comprising mesenchymal stem cells expressing TRAIL and CD as an effective ingredient for prevention or treatment of cancer. A pharmaceutical composition comprising TRAIL- and CD-expressing mesenchymal stem cells as an effective ingredient for prevention or treatment of cancer according to the present invention induces cancer cells to undergo apoptosis, thereby inhibiting cancer cell formation and metastasis. In addition, as immortalized mesenchymal stem cells that have a high cell proliferation rate, the mesenchymal stem cells are unlikely to abnormally differentiate due to the stable expression of an introduced gene because the cells can regulate the expression of TRAIL protein and CD protein therein according to treatment with or without doxycycline, and are of high stability because apoptosis is induced by 5-FC treatment to allow the removal of residual stem cells. In addition, cell lines expressing both TRAIL and CD were observed to have excellent anticancer effects. Therefore, the pharmaceutical composition of the present invention can be effectively used for prevention or treatment of cancer.

Abstract: ﻿The invention relates to sports apparatuses with unstable surface intended for improving and maintaining ones physical condition. The sports apparatus according to a first embodiment comprises a flexible shell formed as a hermetic chamber with a valve and having an inner space for filling with a filler material and/or air. The hermetic chamber is accommodated within a case with handles. Once the chamber inner space is filled with a filler material and/or air, the sports apparatus in fact forms a rectangular parallelepiped with rounded corners. Side faces of the apparatus form a closed surface. The side face has a height not exceeding a half of the apparatus length. A supporting portion of the apparatus and a portion that the user interacts with are arranged to be identical and outwardly convex. The sports apparatus in operating condition has an elliptical cross-section. Said sports apparatus portions are unstable surfaces. The hermetic chamber valve is operative to adjust the air pressure within the chamber. The case is made of a strong non-slip fabric. The hermetic chamber is made of a polymeric material. The filler material comprises a material able to migrate readily within the chamber. Handles are arranged on a side face of sports apparatus case. A hole to access the hermetic chamber valve and a valve for removing the chamber from the case are arranged on a side face of sports apparatus case. A second embodiment differs in that the apparatus has no shell. The proposed structure of the apparatus makes it possible to improve the training efficiency owing to unstable surface enabled by the apparatus shape and also by the filler material and air.

Title: Cerrahi bir acil olan pnömotoraks müdahalesinde çok daha hızlı ve etkin girişim yapabilmenin yanı sıra mobilizasyon problemini ortadan kaldıran yeni bir tedavi cihazı: P-Kit.
Inventor: ÖMER YAVUZ
IPC: A61M39/00
Filed: 2022-06-28
Abstract: Cerrahi bir acil olan ve özellikle göğüs cerrahisi branşını ilgilendiren pnömotoraks; göğüs kafesi içinde, akciğer dışında hava birikimi olarak tanımlanır ve acil müdahale edilmediği durumlarda hayatı tehdit eder. Müdahalede tüp torakostomi (TT) adı verilen işlem yapılır. TT hastane şartlarında, genellikle lokal anestezi eşliğinde, cerrahi aletler (pens, penset, portegü, vb) ve sarf malzemeleri (bistüri, toraks dreni, toraks şişesi, süturlar, vb) kullanılarak yapılan ve oldukça ağrılı olabilen, dahası; işlem sonrasında ağrıların sıklıkla devam ettiği bir prosedürdür. TT işlemi esnasında göğüs duvarı yan tarafından bistüri ile yaklaşık 2 cm boyutunda açıldıktan sonra cilt altındaki dokular ve ardından kaslar künt olarak geçilir ve göğüs boşluğuna ulaşılır. Bu işlem ağırlıklı olarak doku makası veya pens adı verilen kilit mekanizmalı bir cerrahi alet yardımıyla yapılır. İşlem esnasında makas veya pensin akciğere veya kalbe fiziksel zarar vermesi mümkündür. Göğüs boşluğuna ulaşıldıktan sonra ciltteki açıklıktan toraks dreni adı verilen boru, yaklaşık 15-25 cm aralığında içeriye gönderilir. Toraks dreni göğüs duvarına iç kısımdan temas halinde kalır ve plevra adı verilen akciğer zarına temas ederek, çoğu sefer omuza vuran ağrıya sebep olur. Ardından süturlar yardımıyla toraks dreni cilde tespit edilir ve toraks dreninin ucuna, kapalı su altı sistemi olan toraks şişesi bağlanır. Toraks şişesinin görevi tek taraflı hava akışı sağlamaktır, böylelikle hasta öksürdüğünde veya nefes verdiğinde serbest hava şişeden dışarıya çıkarken, nefes aldığında içeriye hava girmesi mümkün olmayacaktır. Tüm bu tertibat (cilde tespit edilmiş toraks dreni ve ona bağlı olan toraks şişesi) hastanın yanında, yürüdüğünde eliyle taşıması gereken hantal bir yapıdır. Pnömotoraksın ortalama tedavi süresi 3-7 gündür. Bu süre boyunca hasta toraks şişesini yanında taşımak durumundadır, dahası; bu haliyle hastaneden çıkışı yapılamamakta ve toraks dreninin çekilmesini hastanede beklemesi gerekmektedir. P-Kit, teknik olarak temelde göğüs cerrahisi branşını ilgilendirir. P-Kit pnömotoraks varlığında tüp torakostomiye göre çok daha hızlı müdahale imkânı sağlayacaktır. İşlem öncesi TT?de olduğu gibi lokal anestezi yapılabilir ve ardından başkaca bir cerrahi alet gerektirmeksizin uygulanabilir. Tüp torakostomiden çok daha hızlı olduğu gibi hastanın hastanede kalma zorunluluğunu ortadan kaldırır. Dışarıdan bakıldığında hastanın pnömotoraks hastası olduğu anlaşılmayacaktır. Valfli sistem sayesinde hava akımı sadece dışarıya olduğu için göğüs kafesi içine herhangi bir bulaş söz konusu olmayacaktır.

Abstract: La présente invention a trait à des dispositifs et des procédés permettant le dégonflement d'un élément de garniture d'étanchéité en cas d'urgence où il se produit une perte d'alimentation vers la pompe de gonflement. Un ensemble de garniture d'étanchéité gonflable comportant des éléments de garniture d'étanchéité gonflés de manière sélective par du fluide pompé à partir du trou de forage à travers un tube de gonflement dans les éléments de garniture d'étanchéité. L'ensemble de garniture d'étanchéité comporte une réduction de dégonflement renfermant des éléments constitutifs du mécanisme de dégonflement d'urgence. La réduction de dégonflement définit une chambre de déversement qui est plus ou moins à la pression atmosphérique, maintient une portion de la ligne de gonflement pour l'élément de garniture d'étanchéité et un moyen permettant la séparation de la ligne de gonflement. Pour actionner le mécanisme de dégonflement d'urgence, un opérateur tire sur le train de tubage. Un piston est alors déplacé en direction axiale par rapport au boîtier, provoquant la séparation de la ligne de gonflement. Du fluide en provenance de l'intérieur des éléments de garniture d'étanchéité est alors libéré pour pénétrer dans la chambre de déversement pour le dégonflement des éléments de garniture d'étanchéité. Etant donné que les éléments de garniture d'étanchéité sont soumis à la pression hydrostatique externe, le contenu de fluide s'écoulera naturellement dans la chambre de déversement.
